NOZZLE FOR PNEUMATIC C-OTTON-PICKERS.

Specification of Letters Patent.

Patented Jan'eo, 1920.

Application filed August 2, 1919. Serial No. 314,972.

To all whom it may concern:

Be it known that I, CONRAD S. MATTHIES- SEN,- a citizen of the UnitedStates, and a resident of Philadelphia, in the county of Philadelphiaand State have invented certain new and useful Improvements in Nozzlesfor Pneumatic Gotton-Pickers; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in nozzles for pneumatic cottonpickers and it consists in a tapering nozzle having means for. forciblyremoving the cotton from the pod and holding it in a position where itwill be drawn into the nozzle by thev pneu-.

matic or suction device.

It further consists in details of construction and combination of partsas will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspectlve ofmyimproved nozzle; Fig. 2 .is a view in side elevation of the same, andFig. 3 is a front end view.

1 represents the nozzle having an out-- wardly tapering or flaring frontend 2, and a cylindrical rear end 3, which latter is designed to'beconnected by a flexible hose, with a suitable suction device, such forinstance as shown in my pending' application No. 256,407, filed October1st, 1918. One side of the tapering end 2 is flattened as at 4, topermit the levers 5 and 5* carrying the jaws 6and 7 to be located closeup to the nozzle-and also to avoid the use of unnecessarily long jaws.

The levers 5 and 5 and the jaws 6 and 7' are preferably made in onepiece of flat strip metal as shown, their rear ends being connected bythe bent section 8 preferably integral with the levers and constitutinga spring which normallyholds the jaws 6 and 7 separated as shown inFig. 1. p 4 The jaws 6 and 7 are referably integral with'the levers andare ormed by bending the free ends of the latter -atright-angles so asto extend across the open end ofthe tapering nozzle 2. The lower jaw 6is constructed to present a flat side or seat for engagement with thecotton boll or pod, while the upper jaw 7 presents anarrow edge,approximately the thickness of the metal strip, which coacting with theflat jaw 6 operates by a slight of Pennsylvania,

pull to loosen the cotton from the pod, thus leaving the' cotton free tobe drawn into the nozzle by the suction.

While I have shown the jaws 6 and 7, integral with the levers and formedby bending the free ends of the latter at right angles, it is clearlyevident that they may be made separate from the levers and-secured tothe latter. The portions of the levers 5 and 5 adjacent the jaws arebent inwardly as shown at 9 toward the nozzle for shortening the jawsand at the same time leaving sufficient spacebetween the levers and thenozzle for the free manipulation of levers by the hand. The handleportions of the levers are preferably rounded as shown to permit them tobe conveniently manipulated.

The levers are secured at their rear ends to the nozzle by the metalstraps 10 and 11, the former of which passes over the topof the nozzleand down and through a loop 12 in one end of the strap 11 and is securedto the spring member 8 adjacent lever 5 The strap 11 embraces the lowerside of the nozzle and is secured 'at its free end to the free end ofthe strap 10 by the screw 13 and nut 14;.

The upper lever is provided adjacent its outer end, with the elongatedslot 15 to receive the bolt'16 carried by the arm 17 rigidly secured tothe flattened face 4 of the tapering end 2 of the nozzle, the leverbeingheld in place thereon by the nut.18. By means of thestrap'connections 10 and 11 and the slot for the bolt 16, the levers maybe adjusted to carry the jaws toward oraway from the 'open end of thenozzle as may be desired." N

As before stated the nozzle is attached at its rear end 3to a flexibletube connected .between the jaws, the flat upper jaw is forceddownwardly thus clamping the cotton between the flat upper aw and thecomparatively thin edge of the lower jaw. A slight pull on the cottondetaches it from the pod and the loose cotton is then drawn by thesuction into the nozzle and through the fiexiblepipe to the container.

I1; is evident that many slight changes in the details of constructionmay b e resorted to without departing fromthe sp1r1t of my invention,hence I would have it understood that I do not confine my inventiontothe details shown but consider myself at liberty to make such changes asmay come within ters-Patent, is

the spirit of my invention and the terms of the claims.

Having fully described my invention What I claim as new and desire tosecure by Let- 1. In a cotton picker, the combination of a suctionnozzle, leversat one side thereof,

each lever having a'jaw located in advance of the open end of thenozzle, one of said jaws being fixed and the other movable, and.

toward and away from the fixed jaw, and a spring for normally holdingthe levers and jaws separated.

3. In a cotton picker, the combination of a suction nozzle, leversadjustably mounted. on said nozzle, each lever having a jaw extendingacrossthe open end of the nozzle and a spring for normally holding thelevers and jaws in open or separated posi-' tlon.

4. In a cotton picker, the combination of a suction nozzle, leversadjustably carried by said nozzle, one of said levers being fixed andthe otherimovable, and each lever having a jaw extending across the openend of the nozzle and a spring for holding the levers and jaws normallyseparated r In testimony whereof I have signed this specification in thepresence of two subscribing witnesses.
